do the cognito uca actually make the truck ride better when you crank keys? i have a 04 sierra hd and cranked the keys almost to where they bottom out and it rides okay, just not the greatest. i was planning on getting the ucas and new shocks(what would be the best shocks for my application? i was think fox or bistein) so it rides good again. also do the shock extenders help? so i was pretty much wondering if any one has the cognito leveling kit and has it pretty cranked up and how it rides? i pretty much want a review on the kit and pics, lots of pics.... thanks guys!!
